To all 'whom t may concern.'

Be it known that l, Nazznnnrio TocNAccr, a subject of' the King ofltaly,residing at Kincaid, in the county of Christian and State of lllinois,have invented certain new and useful improvements in Ship-RaisingDevices, of which the following is a specification. v

The primary obj ect of the invention is the provision of adevicefadapted for raising sunken vessels to the surface of the watereasily and quickly, the device possessing great strength and beingsimple in constructionv A further object of the invention is to providea pneumatic means for raising sunken vessels and providing an arrangement for changing weighted members at tached to the vessel intoelevating floats therefor, the device being readily operable from thesurfaceof the water in the neighborhood of the vessel to be raised.

1With these general objects in 'iew and others that will appear as thenat-ure of the invention is better understood, the same consists ,in thenovel construction, combination and arrangement of parts hereinaftermore fully described, illustrated in the accompanying drawings, and thenclaimed.

ln the drawings forming a part of this application and in which likedesignating characters refer to corresponding' parts throughout theseveral views,

Figure 1 is an elevational view of the device illustrated in itsoperative arrangement in raising a sunken vessel.

Fig. 2 is a sectional view of one of the floats having an attachingchain with a vessel indicated by dotted lines supported by the chain.

Fig. 3 is a similar view of one of the floats during the inflationthereof.

Fig. 4; is transverse sectional view of a float taken upon line Tlf-1Vof Fig. 3 and Fig. 5 is a diagrammatical View of the operating pump andpiping employed with the floats.

Referring more in detail to the drawings, a sunken vessel 10 is hereinillustrated resting upon the bottom 11 of the ocean 12 while a ship 13upon the surface of the water vis provided with my device by means ofwhich the vessel 10 may be easily raised to a point alongside of theship 13.

il. plurality of hollow glol dar preferably n :metal floats lareprovided, substantially pearshape'd as herein shown having an inlet head15 at one end and a .valve casing 16 at its opposite end foraccommodating an outlet valve 1T. This falve is normally closed by meansof the water pressure when the float '14 is submerged while a handle 1Sis provided for the said valve 17 for opening the saine when desired.

ppositely arranged hooks 19 are provided upon the head 15 with theopposite ends of a chain 20 positioned upon said hooks, thereby forminga. chain loop adapted for positioning around the vessel 10 for raisingthe same. A weight 21 is preferably provided for each of the chains 2Oand it will be understood that divers will be employed for positioningthe chains 2O around the vessel 10 and then attaching the chains to thehooks 19 ofthe floats 14, the said floats being adapted to be filledwith water for sinking the floats to'a point adjacent the deck of thesubmerged vessel.

lVith the water filled floats 14 connected to the vessel 10 in themanner described, a combined elevating water pump and air compressor 22which is arranged at any convenient point upon the ship 13 is employedfor pumping the water out of the floats llland forcing air into tliefloats foi-.taking the place of' such water.

The valve casings 16 are connected to the water pumping side 23 of thepuni 22 by means of suitable pipes 24: while tie inlet heads of thefloats ll are connected to the air compressing side 25 of the pump 22 bymeans of suitable hose 26.

With the device arranged as shown in Fig. 1 of the drawings, it will beunderstood that by operating the pump 22, the water 2?' within thedoa-ts 1d will be extracted 'therefrom through the pipes 2li while airwill be pumped into the floats 121 through the bottom heads 15 by theuse of the hose 26. El. funnel or injector tube 28 is carried bythevalve casing 16 of each float 1d and axially posi-y :les

iie

simultaneously with the How of air into the oats through the hose 26. Aserviceable device for quickly raising Sunken vessels is provided whichrequires only a few workmen and divers and has but few parts and theseare only slightly liable to injury.

What I claim as new is 1. A device of the class described comprising ahollow Vertical fioat, an inlet head at the lower end of the float, avessel engaging chain suspended from said head, air supplyin hoseattached to said head, and a s 'ater ex iausting pipe connected to theupper end of the float. l

2. A device of the class described comprising a hollow vertical float,an inlet head at. the lower end of the float, a vcseel engaging chainsuspended from said head, air supplying hose attached to said head, awater exhausting pipe connected to the upper end of the lloat, aninjector tube within the float between the air inlet and Water outletvends thereof,and a com'bined water pump and air compressor arranged at adistance from the float operatively connected to said pipe and saidhose. 4 s

A vessel raising float comprising a substantially pear-shaped verticalhollow body,

neoaaae an inlet head at the lower end of the body,

chain suspending` means carried by said head, an air supplying hoseconnected to said head, a valve casing at the upper end of the body, awater exhaust pipe attached to said casing, al valve within the Saidcasing, and a funnel-shaped member axially within the body secured tosaid casing at the Smaller end and with its open larger end po sitionedadjacent said head.

` l. A vessel raising lioat comprising a substantially pear-shapedvertical hollow body, an inlet head at the lower end of the body, an airSupplying hose connected to said head, a valve casing at the upper endof the body, a wat-er exhaust pipe attached to said casing, a Valvewithin the said casing, a funnel- Shaped member axially arranged withinthe body secured to said easing at the smaller end and with its openlarger end positioned adjacent said head, a vessel engaging chaindetachably suspended from said head, a a

weight carried by said chain, anda combined water pump and aircompressor operatively connected to the said hose and said pipe.

In testimony whereof l affix my signature.
